Dell EMC PowerEdge R430 for master node, login node and CIFS gateway
The solution includes four Dell EMC PowerEdge R430 servers. Two of these servers are designated as login nodes. Users can log in to
these nodes and submit, monitor or delete jobs. The other two nodes function as redundant head nodes for the cluster, which are used
by Bright Cluster Manager® to provision, manage and monitor the cluster in a high availability (HA) configuration. The head nodes are
in an active–passive HA state and use the NSS7.0-HA solution as shared storage.
Storage Components
The storage infrastructure consists of the following components:
o Dell EMC Ready Bundle for HPC NFS Storage (NSS7.0-HA)
o Dell EMC Ready Bundle for HPC Lustre StorageDell EMC PowerEdge R430 as the CIFS Gateway
NSS 7.0 HA
NSS 7.0 HA is designed to enhance the availability of storage services to the HPC cluster by using a pair of Dell EMC PowerEdge
servers with PowerVault storage arrays, Red Hat HA software stack [7] and a network switch. The two PowerEdge servers have shared
access to disk-based Dell EMC PowerVault storage in a variety of capacities, and both are directly connected to the HPC cluster using
OPA, IB or 10GigE. The two servers are equipped with two fence devices: iDRAC8 Enterprise, and an APC Power Distribution Unit
(PDU). If system failures occur on one server, the HA cluster will failover the storage service to the healthy server with the assistance of
the two fence devices and also ensure that the failed server does not return to life without the administrator’s knowledge or control.
